It would be silly to declare trends or patterns this early in the season, but the Texans have shown some things about themselves as they rolled to a 2-0 start. The Texans followed a 20-point win over the Miami Dolphins with a 20-point win over the Jacksonville Jaguars.

Here's what we've learned about the Texans.

1. J.J. Watt is very good. Like superstar good. His teammates can't tell us enough that nobody should be surprised by his play, but batted passes seem so flukey (though they really aren't) that it is newly impressive every time he gets his hand on one. It's not like the Jaguars didn't expect this. When I talked to head coach Mike Mularkey on Friday, he talked about the importance of offensive linemen making defensive linemen pay for throwing their hands up like that when they can't get to the quarterback. A punch to the gut ought to do it. But whatever the Jaguars line did, wasn't enough. Watt had five tackles, 1.5 sacks, two tackles for loss, three quarterback hurries, two passes defended and one fumble recovery. Only one word for that: Wow.

2. The Texans are fast learners. One week after there was much panic about the Texans' running game, those issues disappeared. Both Arian Foster and Ben Tate had tremendous games Sunday and combined for 184 yards. The mark of a good team is the ability to learn from their mistakes, fix it and move on. Special teams also improved significantly from a subpar Week 1.

3. Preparation is key. After the Texans' win over the Dolphins, players on offense and defense said they saw things from the Dolphins they hadn't quite seen on film. Last night I heard some variation of "we knew exactly what they were going to do" from every member of the secondary. The result? Fifty-three passing yards for Blaine Gabbert, 0-for-9 third-down conversions and a receiving corps that couldn't make much happen at all. The Jaguars' didn't get Justin Blackmon involved and the only two players to catch all the passes thrown their way were running back Maurice Jones-Drew (three for three) and fullback Greg Jones (one for one).
